IMPROVEMENT 1N cHlLoRENs eARnlAeEs.`

The Schedule referred to in these Letters Patentand making part of the same.

l, RODNEY G. BRITTON, of Springfield, in the county of Windsorand State of Vermont; haveinvented an Improvement in 'theGonstruetion of Childrens Carriages, of which the following is a specification.

My inyention consists in forming the connection between the forward axle and the body 0r arms, which are pivoted'to the latter, with a spring or springs interposed in sueh a manner as to allow the front wheels to accommodate themselves t0 the inequalities ci the ground, or one to pass overa raised obstruction wit-hout raising the other or tipping the carriage, and also to diminish the effect upon the occupant ot' the carriage ot' 4the shock of striking such obstacles.

Figure 2 is an enlarged detached View of one of the t similar effect.

reach-arms' and springs; and

Figure 3 is a modification, in which a single halfelliptic 'spring is made to serve for both reach-arms, the latter being shown in section.

-As represented in thedrawingv- A is the body ot'- an ordinary ehilds carriage;

B., the hind, and

JG, the tbrward wheels. p

The axle of the former is connected with the'rear portion ofl the `body by C-springs, in the ordinary manner; but the axle, instead ot' being eonnected with the body by a rigidiy-attached reach or reacharins, has those arms G G attached to the body bymeans of the pivoted fastening d, on which they are at liberty to vibrate when the forward Wheels are passing over an irregular surface, orthat one may yield, if a single wheel is raised, without aifecting the other.

Between theV pivot d Vand the body, preferablyforward of the joint, I interpose a spring, e, of such form and so connected either with the arm orthe body that it will keep the body from resting direct-ly on the arm,

Aaud'by yielding, when the force of one or both of the is separately pivoted, one wheel may rise or sink, the v axle inclining therewith without tipping the body of the carriage.

rIhe arms may or may not. work in guides j', which also serve to keep the free ends of the spring in place. I prefer to use a separate spring, which may be flat, coiled, or of any shape to. give the requisite elasticity; but the same'resnlt may be produced in nearly as effectual, though not as economical, a manner by em ploying a single half-elliptic spring, iig. 3, each end bearing upon one of the'arrns, and the center supporting the body to which it is attached, as shown in iig. 3. A single .reach-arm and spring,I or the two eon verging to the center of the axle, may be used with -a Not only does this improvement secure elasticity to the body upon the forward axle, but it allows the body to vibrate more freely on the rear springs by transferring the center of motion to the joint d. It is iuexpensiye, and addsfto the durability by modifying the severity of the resistance encountered by the forward wheels, as well as promoting the ease and comfort of the rider. f

I claim as my inventionthe body A, within Vfastenings, with the interposed` spring or springs c, substantially as and.for the purpose set forth.

In witness whereofI have hereunto signed my name in the presence of two subscribing witnesses.
